Product details
Overview
LPC1111FHN33/201 from NXP Semiconductors is an ARM Cortex-M0-based 32-bit microcontroller in a 33-terminal HVQFN package, featuring 8 kB flash, 4 kB SRAM, one UART with RS-485 support, one Fast-mode Plus I²C interface, one SPI, four general-purpose timers, and an 8-channel 10-bit ADC-designed for low-power industrial sensor nodes and embedded control systems.
For engineers reviewing the LPC1111FHN33/201 datasheet, LPC1111FHN33/201 pinout, LPC1111FHN33/201 application, or LPC1111FHN33/201 equivalent, key selection criteria include its 50 MHz CPU clock, 3.3 V single-supply operation (1.8–3.6 V), Deep-sleep mode wake-up via up to 13 GPIO pins, programmable power profiles, and compatibility with ISP/IAP firmware updates.
Technical Context
The LPC1111FHN33/201 implements the ARM Cortex-M0 core with NVIC and SysTick timer, executing instructions at up to 50 MHz using either the internal 12 MHz ±1% RC oscillator or an external crystal (1–25 MHz). Its clock system includes a PLL, programmable watchdog oscillator (7.8 kHz–1.8 MHz), and clock output divider supporting CPU, IRC, system oscillator, or WDT clock reflection.
Power management is handled by an integrated PMU enabling Sleep, Deep-sleep, and Deep power-down modes; the LPC1111FHN33/201 belongs to the LPC1100 series and therefore lacks page-erase In-Application Programming (IAP) and dual-SPI capability-features reserved for LPC1100XL variants-while retaining full UART, I²C, and timer peripheral functionality.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LPC1111FHN33/202 | Same 8 kB flash / 4 kB SRAM, but belongs to LPC1100L series with power profiles enabled | Supports optimized Active/Sleep power profiles; suitable where dynamic power scaling is required | Select when application requires runtime power mode switching without firmware overhead |

FAQ
What is the maximum operating frequency of the LPC1111FHN33/201?
The LPC1111FHN33/201 operates at a maximum CPU frequency of 50 MHz, achievable using either the internal 12 MHz ±1% RC oscillator with PLL multiplication or an external crystal (1–25 MHz) directly driving the system clock. This frequency is fully supported across its −40 °C to +85 °C operating range and enables efficient execution of real-time control algorithms in compact embedded designs.
Does the LPC1111FHN33/201 support In-System Programming (ISP)?
Yes, the LPC1111FHN33/201 supports In-System Programming (ISP) via its built-in ROM bootloader, accessible through UART (using PIO1_6/7 as ISP_RXD/ISP_TXD), I²C, or USB (when paired with external PHY). The bootloader occupies fixed flash space and enables firmware updates without external programming hardware-critical for field-deployed devices where physical access is limited.
How many ADC channels does the LPC1111FHN33/201 provide, and what is their resolution?
The LPC1111FHN33/201 integrates a 10-bit successive approximation ADC with input multiplexing across 8 dedicated analog input pins (AD0–AD7). It supports single-ended conversion only, with programmable sample rates up to 400 kS/s, and is commonly used for sensor signal conditioning, battery voltage monitoring, and user interface feedback in resource-constrained applications.
Is the LPC1111FHN33/201 pin-compatible with other LPC111x HVQFN33 variants?
The LPC1111FHN33/201 shares identical pinout and package dimensions (HVQFN33, 7 × 7 × 0.85 mm) with all other LPC111x HVQFN33 variants-including /202, /203, /101, and /102-enabling mechanical interchangeability. However, functional differences (e.g., power profile enablement, SPI count, IAP features) require firmware validation before substitution in existing designs.
What debug interface does the LPC1111FHN33/201 support?
The LPC1111FHN33/201 supports Serial Wire Debug (SWD) as its primary debug interface, using SWCLK and SWDIO pins for full JTAG-like functionality-including breakpoints, watchpoints, and real-time register/memory access-without requiring additional pins beyond the standard two-wire connection. SWD is compatible with standard ARM debug probes (e.g., SEGGER J-Link, CMSIS-DAP adapters) and integrated development environments like Keil MDK and Arm GCC toolchains.
